Snow tires have coarser grooves to clear the snow and provide better traction while being softer in colder weather (it is recommended to *not* use all season tires lower than 7 degrees Celsius as they become too hard and lose their grip. To complicate things further, some winter tires allow the use of studs (and [some come with studs](https://www.canadiantire.ca/en/tires/pdp/pirelli-winter-ice-zero-studded-tire-4080629p.4080635.html?gclid=CjwKCAiAws7uBRAkEiwAMlbZjuXl__VSXE-4csChj9dP_WP9rZfHh7vVDWzwD2jqQWUTLpYibNw0GBoCRFQQAvD_BwE&gclsrc=aw.ds#store=70) that provide better grip in winter weather.
Chains can come off and on with some effort, studs are permanent unless you want to take a lot of your time installing them and taking them out again. And thene there are [these](https://www.youtube.com/watch?v=IPd3O5_SJEs) little beauties.
